Can't get OpenCL to work on Win 7 and VS2010

Hi,

I am using Visual Studio 2010 on a Dell Precision T3500 workstation. It has a Intel Xeon quad-core CPU and an ATI FirePro 4800 graphics card. I installed the latest AMD APP SDK and followed all the instructions given in the "Introduction to OpenCL Programming" guide and tried to get the "Helloworld" program running -- but it is not. It gives the error -- "unable to get device_id".

 

When I run the "clinfo" program, I get the following output:
